Below you can see the front view size comparison of Sony A6300 and Sigma Quattro H. Sony A6300 is clearly the smaller of the two cameras. Its body is 27mm narrower, 28mm shorter and 42mm thinner than Sigma Quattro H.

Now lets look at the top view comparison of Sony A6300 and Sigma Quattro H.

Weight is another important factor especially when deciding on a camera that you want to carry with you all day.
Sigma Quattro H is 404g lighter than the Sony A6300 but we don't think this will make a significant difference.

Also keep in mind that body weight is not the only deciding factor when comparing two interchangeable camera bodies, you have to also take into account the lenses that you will be using with these bodies. Since Sigma Quattro H has an APS-H sized sensor and Sony A6300 has a smaller APS-C sensor, Sony A6300's lenses for a similar focal length and aperture will generally be lighter and smaller than the Sigma Quattro H lenses.
